    Henry works in a factory. He comes from a poor family and was in school for only four years. He has

to do the hard work but he's paid less. He likes to watch football matches very much and spends much

time on it.

     One afternoon there was a big football match on a playground. He borrowed some money from

his friend and hurried there. There were a lot of people there. And all the tickets were sold out. He was

sorry for it. He saw a pole (杆子) outside the playground and climbed up the pole quickly. A policeman

came and said, "It's dangerous to stay on it! Come down!"

     "Wait a minute, please!" Henry said and immediately the policeman heard the cheers (欢呼) in the

playground and asked in a hurry, "Which team has scored a goal (进球)?" "Ours!" "Wonderful! You can

stay there. But be careful!" the policeman said happily and left. A few minutes before the match was over,

he came back again and asked, "Who's won?" "Theirs, three to two." "Come down," the policeman said

angrily. "Such a match isn't worth watching!"

     Henry had to come down. But soon they heard cheers again. The policeman said in a hurry, "Climb up

quickly and see who's scored a goal!"
